Abstract: Registration and inspection systems and methods for use on a winder are disclosed. The systems and methods include scanning a region proximate a winding module with one or more sensors to determine a product defect.

Abstract: There is provided a method of winding up a transfer film and a device for performing transfer printing on printed sheets of paper, capable of eliminating the need to frequently replace the transfer film, thereby allowing the transfer film to be used over a prolonged time. According to the method of winding up a transfer film, the transfer film fed from a feed roll through a feed path is pressed onto a fed printed sheet to transfer patterns of the transfer film, and then the transfer film is wound up onto a windup roll through a windup path. During the rewind of the transfer film from the windup roll to the feed roll, a lateral position of the transfer film running along the feed path is detected, and the feed roll is moved in its axial direction to follow a lateral positional change of the transfer film.

Abstract: Method and apparatus for dynamic tracking of a belt as it is built on two rotatable drums separated by a center-to-center distance, especially during the cording process. In one embodiment, both edges of a belt component are temporarily equipped with corded edge binding which is engaged in a gap formed between upper and lower tracking wheels to provide proper alignment of the belt during the cording process and subsequent building steps. In a first tracking assembly, one pair of tracking wheels operates to constrain and align one edge of the belt and another pair, transversely spaced from the first pair, operates to constrain and align the second edge of the belt in the upper span of the belt immediately prior to the belt being positioned on a first drum. In each wheel pair, the axes are biased toward one another and slightly biased in the direction of travel of the belt.

This device has a spindle (21) which is mounted inside a hollow shaft and onto which the strip is wound; for this purpose the spindle is rotated by a motor (20) which actuates the hollow shaft by means of a mechanical transmission. In accordance with a preferred embodiment, the position of the hollow shaft along the axis of rotation may be adjusted by means of hydraulic actuators, in such a way as to compensate for any winding defects in the coil present on the spindle.

Abstract: An active feedback levelwind apparatus and method for winding cable on a drum has a rotary encoder providing signals representative of drum rotation and a shuttle adjacent the drum receives, bidirectionally moves and wraps the cable on the drum. An outboard sensor assembly on the shuttle has an angular sensor providing signals representative of the angle of extension of an outboard extending portion of the cable. An inboard sensor assembly on the shuttle has an inboard sensor providing signals representative of the angle of extension of an inboard extending portion of the cable. A stepper motor coupled to a computer system bidirectionally displaces the shuttle and cable in response to the rotation signals, outboard angular signals, inboard angular signals and limit signals to smoothly wind the cable. Error position feedback signals from the computer system create corrective displacements for the shuttle to smoothly wind cables of varying widths.

Abstract: In the method for controlling the structure of a reel, a continuous paper web (W) is reeled around a reel spool (2) to form a reel (R), and one or more variables are measured from the web (W). When a particular, predetermined change occurs in the variable, the lateral oscillation of the web is changed, by means of which the web is guided to different locations in the reel (R) in the axial direction of the reel spool (2). The change can be implemented by starting the oscillation or by changing the oscillation in progress. The change can be implemented on the basis of the changes in the transverse profile of the web (W).
